Cox Nissan Complaint - Parts covered under warranty

BRONX, NEW YORK -- My vehicle was under warranty and I brought it over to COX NISSAN located at 3700 Boston Road, in the Bronx, New York 10469. The vehicle that I have is a 5 speed manual transmission, the clutch cylinder was defective and I brought it over to COX for repair. I knew the problem was the cylinder because the clutch pedal would stick to the floor. The clutch clyinder and hose were parts covered under warranty, and after holding my car for about a week, another defective clutch cylinder was put into my car, and I was told that I had to pay $1,000.00 dollars for a new clutch. I spoke to the manager, Mr Badu, and he promised me that he spoke to the head mechanic or engineer there, and the problem was my clutch. I had my car towed to someone who does good work and is trust worthy, and he replaced the hose, and the cylinder for $300.00 dollars. My vehicle drove great. I went back to Mr Badu and he said he would try to refund me my tow fee, my parts and labor, and the money I paid to them for the so called work they claimed they did, he orderd a tire for me, and was suppose to refund the difference, but to this day which has been over a year, he still gives me the run around, he claims that he needs the old clutch cylinder to refund my total. Most car service centers are rip offs, they try to find ways to make you pay for things that are covered under warranty. COX Nissan is well known for this from other consumers I spoke to, most just don't feel they have the time to complain, or don't know how, or it is too time consuming for them. This problem should have been taking care of along time ago, I even spoke to the owner of that establishment, he told me that I would be taken care of, and Mr. Badu would handle my problems, I left him various messages, and he still did not respond.
